Prototype Diesel 10

Diesel 10 is a evil diesel and the main villain of Thomas and the Magic Railroad, Day of the Diesels and in Season 17 episode "The Missing Christmas Decorations."

Bio: Diesel 10 hates the steam engines and want to destroy a magic engine named Lady and the Magic Railroad. He tricked Percy to take over the Steam Works and he stole the Steam Team's Christmas decorations.


  • Diesel 10 is very similar to Head Wolf from Alpha and Omega 4 because they both want a female charther to kill destroy (like Head Wolf wants to kill Daria and Diesel 10 wants to destroy Lady).
